Hood Cleaning Frequency

A commercial kitchen’s hood-cleaning schedule should reflect its cooking volume, equipment and actual grease buildup. A fixed twice-a-year routine can be too infrequent for a busy kitchen. Pristine Shine helps Utah operators assess their exhaust systems and plan recurring cleaning.

Inspection and Cleaning Are Different

NFPA 96 addresses commercial cooking ventilation and fire protection, including exhaust-system inspection and maintenance. Inspection checks for grease accumulation and system conditions. Cleaning removes the deposits. An inspection interval is not a promise that a kitchen can safely wait that long between cleanings.

What Changes the Right Schedule?

Operating hours, cooking volume, menu, fuel type, charbroiling, grease production and exhaust-system configuration all matter. Conditions in the duct and roof fan may differ from what staff can see at the hood. Manufacturer instructions and the local fire authority’s requirements also need to be considered.

When Might Three or Four Cleanings a Year Make Sense?

If a kitchen repeatedly develops substantial grease buildup before its next scheduled service, the interval needs to be reassessed. Moving from two visits to three or four may be appropriate for some operations. That decision should be based on observed conditions and applicable requirements, rather than treating one schedule as sufficient for every restaurant.

What Should Managers Track?

Keep the last service date, equipment covered, before-and-after photos, access limitations and any recommendations for follow-up. Note changes in hours or cooking equipment. Reviewing those records makes it easier to identify systems that accumulate grease faster and adjust the next visit.

Does a Clean Canopy Mean the Whole System Is Clean?

No. Grease may remain in ductwork or the exhaust fan even when the visible hood looks clean. The written service scope and report should identify the components cleaned and any inaccessible areas. Access problems need an agreed follow-up plan.

Does Hood Cleaning Cover Fire Suppression Service?

No. Suppression systems and portable extinguishers have their own inspection and maintenance requirements. Keep their service records and due dates separate from the exhaust-cleaning schedule. Learn about kitchen fire protection service.

Confirm Your Kitchen’s Requirements

Use the applicable adopted standard, equipment instructions and direction from your local fire authority when setting the maintenance plan. The newest published standard is not automatically the edition adopted in every jurisdiction. Our guide helps with planning; it does not replace a site-specific assessment.
